I'm modeling some industrial equipment. Each "component" is stored in its own geode and the geodes are connected together by MatrixTransform nodes. The components are all connected to each other, and spatially, some components are siblings to each other and others are connected in a parent-child relationship. It just turns out that there isn't a single "root" component in the most obvious arrangement. I can reorder things and then I do get a singly rooted graph, but it isn't quite as natural.
